Abstract

Obesity‐induced chronic inflammation is a key component in the pathogenesis of insulin resistance and the Metabolic syndrome. In this review, we focus on the interconnection between obesity, inflammation and insulin resistance. Pro‐inflammatory cytokines can cause insulin resistance in adipose tissue, skeletal muscle and liver by inhibiting insulin signal transduction. The sources of cytokines in insulin resistant states are the insulin target tissue themselves, primarily fat and liver, but to a larger extent the activated tissue resident macrophages. While the initiating factors of this inflammatory response remain to be fully determined, chronic inflammation in these tissues could cause localized insulin resistance via autocrine/paracrine cytokine signaling and systemic insulin resistance via endocrine cytokine signaling all of which contribute to the abnormal metabolic state.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Evidence indicates that inflammation causes insulin resistance.

    “Evidence indicates that inflammation causes insulin resistance”
  • Intake of flavonols and flavones was not correlated with plasma CRP or IL-6 concentrations in healthy women with BMI 25.8-26.2 kg/m2.

    “The intake of flavonols and flavones was not correlated with plasma concentrations of CRP or IL-6 in healthy women (BMI 25•8-26•2 kg/m 2 ) (801) .”
  • Several cytokines and chemokines, including CCL2, IL-6, IL-1β, MIF, and TNF-α, can be released by adipocytes and macrophages.

    “Several cytokines and chemokines, such as CCL2, IL-6, IL-1β, macrophage migration inhibitory factor (MIF), and TNF-α, can be released by adipocytes and macrophages (83)(84)(85).”
  • Adipocytes are the unique source of secreted adipokines such as leptin and adiponectin, which can promote insulin sensitivity, and resistin and retinol-binding protein 4, which can impair insulin sensitivity.

    “Adipocytes are the unique source of secreted adipokines such as leptin and adiponectin, which can promote insulin sensitivity, as well as resistin and retinol-binding protein 4 (RBP4), which can impair insulin sensitivity (83)(84)(85).”
  • Elevated levels of TNF-α, IL-6, and C-reactive protein have been shown in individuals with insulin resistance and diabetes.

    “Consistent with this, elevated levels of the proinflammatory cytokines TNF-α, IL-6, and C-reactive protein (CRP) have been shown in individuals with insulin resistance and diabetes (for review, see refs.[83][84][85].”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
